Issue with that is that you can only get lucario after you eat the story. Or you trade on GTS

But ultra necrozma is incredibly fast. It has a 127 speed that’s being doubled. So the only way to outspeed is a priority move or lower it’s speed with something else or boost lucario speed in order for lucario to get a chance to even land the hit. You could try trick room but that Tm is post games so you need to find a Pokémon that learns it naturally. Even then it’s got respectable bulk which also has been doubled. In fact all it’s stats are doubled.

The easiest way to beat it is toxic stall with prankster.

I reckon just keep on looking for ultra moon. You could try to buy it online too
